The Returners from Poland are an example of a new wave of international Hip Hop producers who consistently bring the classic neck-snapping sound into songs with upcoming and established talent, with a fresh, new twist. El Da Sensei and Rakaa sound hungry and determined as ever, that's most likely due to the dope production sound of The Returners. "Knowledge Is The Key" featuring Rakaa Iriscience is the debut single to El Da Sensei & The Returner's forthcoming LP, 'Global Takeover 2: Nu World' (GT2) which drops on October 12th, 2010. Check out the album trailer below, direct from the studio sessions.
